Text in bold means it is a terminal command (NT, OSX, or *nix). Rainbow cracking can greatly reduce the amount of time it takes to crack a password hash, plus you can keep the tables, so you only have to generate them once! Requirements This method works especially well for people with slow processors, since you don't have to compute much. This means that hashes are pre-generated by a computer and stored in a large rainbow table file with all of the hashes and words that correspond to them. Rainbow tables work on the principle of a time-memory trade-off. If there is, the password is correct if not, it will keep guessing. Normally, when you crack a password hash, your computer computes a word, generates the hash, then compares to see if there is a match.
This means we have to crack those hashes! Hashes are made to be one-way, which means algorithmic reversal is impossible. However, after a password is made, the computer stores a one-way hash of the password that obfuscates it. When a password is created, the user types the password in what is called "plain text", since it is in a plain, unhashed form. Passwords are normally stored in one-way hashes. First, let's go over how passwords are stored and recovered.
